To aZZwko'm-it mag/concern:

Be it known that. I, \VALTER G. KING, a citizen ofth'e United States, residing at the city of New York, in .the county of New York and State of New York, have invented certain .new and useful Improvements in lVelding-Shields, of which-the following is H I 2 1s an outside or-front view of a shieldemv a full, clear, and exact description.

My invention relates to weldlng shields forscreening theeyes' and'face from the intense light of aiwelding arc and protectlng the face from the heat and minute flying particles in theregion of the arc, andhas i more especial application to hand shields usedby inspectors for temporary observation as distinguishedfrom the goggles which areWo'rn by the welders. I

By reason of the nature of their use these hand shields are'commonly subjected to more orlessroughlusage, and they are frequentlylaidldown in such proximity to the are" that they are exposed to-a high degree of heat, sometimes actually coming into contact with one of the conductors or electrodes, with the result that i-fther'e is much metal in the 0011-. I

struction, not only is the metal melted or otherwise inj ured, but ascfreqliently happens the operator is liable to receive 'a'severe electric shock. I

Anobjectof my invention is to, 'rovide a" shield of thischaracter which wil be sufli ciently strong'and durable to withstand the ordinary usage, which Will eliminate all leakage of light, in which metal is entirely eliminated or is minimized, and which, while holding the'lensessecurely in place, will enable themto be easily and .conveniently' removed and reinserted,'as theymust be with comparative frequency in use to replace the cover glasswhen it becomes pitted so as to materially impairitstransparency. Other obj ects and advantages of my invention Wlll appear from the following description.

n accordance with my invention I' make the shield entirely of a suitable non-conducting material, such as fiber, and I reinforce the flat central portion with any overlapping fiber sheet which issecured at its bottomend to the inner face of the body ofthe shield, andextends over the observation opening with its upper end and thus screens the lens opening against an possible leakage of light and resiliently olds the'lenses in their frames. Preferably this reinforcing sheetis provided with outwardly turned I lips at the observation opening .to bearhelmets-or 'parts. v c I 'lIo take out the lenses it 1s only necessary -frame, .th'e top'edge. of the sheet being held down by a butto'n'or othersuitable device.

"I shall now describethe illustrated emaafter point out myinvention in claims.

againstthe lenses and holdthemi-n their vertical sectional'elevation on an enlarged scale. 1 a

In the formshown th'e body member 1 is composed of a suitable non-conducting'sheet -:;'r'naterial such as, fiber, whiichis rearwardly bent at the top andfsides ,togive-the -"device the usual-protective semi-eoncavei shape, the

central and bottom portion-being left flat, as

shown, .In the upper. part of thisflat por tion the usual observation opening 2 isprQ- vided, which" is'coveredfbythe' lenses 3 front of which is the' plane cover glass 4; These lenses are seated against'the rear .face

of the body member within ax-frame, 5 of felt or other suitable cushioning and insulating material secured tot'he body-member in any practlcable way, as' by rivets- Overlying theselenses is the reinforcing sheet 6, als'ooffiber, which is secured at its bottom to the .inner face of the body member, as-nby rivets, its upper end which overlaps the lensesbeing'left free, -yided with an observation opening 7 in register with the opening '2, and has outwardly turnedl-ips 8 at the ends of the opening which resiliently bear against the inner face.

the opening 7 and is carried by the sheet of the lenses 3 and retain them on their seat.

A hood or eye shield 9. of'fiber surrounds member 6.- A button 10 pivoted to the body .member is adapted to look over the topedge of the sheet memberi6 when. the device is ready for operation and resiliently hold the lips 8 against the lenses. 1 Secured to the-bottom Oa hs shield is a suitable handle 11 of It will be observed that there is neway for light. to leak throughthe shield since the sheet 6 effectively covers the lens opening.

The sheet 6 also serves to materially rein-L I force. and strengthen the shield. Furthermore, there is; an. entire absence'ofmetal to release thebi tton 10 and .bend back the top of the sheet member 6 sufiiciently to af ford-access'to the 1enses, and they are as easilyinserted and are secured inplace after 1nser t1on 'by merely turning'the button 10. over the top edge oft'he sheet member.

It will be understood that, whilefI have described one way of carrying out my in vention, it is in no wise limited thereto, butthat various modifications may-be made in theillustrated-embodiment Without depart- ,ing from the scope of, the appended claims.

I claim:'
